IMPROVEMENT IN FENCE-WIRE STRETCHERS.

Specification forming part of Letters Patent No. 222,01 3, datedNovember 25, 1879; application filed August 7, 1879.

- in Fence-Wire Stretchers; and we do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

The nature of our invention consists in the construction and arrangementof a machine for stretching wire, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawings, inwhich-- Figure l is a plan view, Fig. 2 a longitudinal section, and Fig.3 a detail view, of our invention.

A represents the frame of our wire-stretching machine, which frame formsahead at one end. On this head is a hollow box, B, serrated on its innersurface, and a cam-lever, O, similarly serrated, is pivoted on the head,and works against the serrated surface of the box to hold the wireperfectly tight.

In the frame A is a slide, D, on which is a box, B, and cam-lever 0,similar to those described on the head of the frame. The side edges ofthe slide D have V-shaped grooves fitting over similar flanges in theframe, as shown at a a. The slide D is, by a cord, 1), connected with adrum, E, placed loosely on a shaft, (1, and connected to said shaft by apawl, e, and ratchet f. On one end of the shaft cl, within a slot ormortise in the frame, is secured a cog-wheel, F, which meshes with aWitnesses:

pinion, G, mounted on a short stud or shaft having a crank, H, on itsouter end for rotat ing the same.

h is a pawl to take into the cog-wheel E to prevent any backward motionthereof;

The head of the frame A has a forked pro jection, I, with a screw, t,passing through the same for attaching the device to a fence-post orother stationary object for use. When thus attached the wire is placedin the box B and held by the cam-lever 0. By now turning the crank H thedrum E will be rotated, the pawl e being in engagement with theratchet-wheel f, and the cord b will draw the slide D forward,stretching and straightening the wire. The wire is then clasped by thecam-lever O in the box B, and the lever C loosened, so that bydisengaging the pawl e the slide can be moved back for the purpose oftaking a new hold, if desired.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

In a fence-wire tightener, the frame A, having the forked projection I,screw i hollow serrated box B, guides a, and cam-lever G, in combinationwith the grooved slide D, having a reciprocating movement in said frame,and provided with the hollow serrated box B and cam-lever O, cord 1),drum E, pawl and ratchet cf, gears F G, pawl h, and crank H, the wholeconstructed and arranged to operate in the manner and for the purposeset forth.

, In testimony that we claim the foregoing as our own invention we affixour signatures in presence of two witnesses.
